Welcome to California! My dealer has a standing policy not to ever charge higher than MSRP (one of the many reasons I keep going back). In fact at one time they had one of two remaining unsold Z8s in the country and still didn't charge above MSRP. I can't prove they honor the waitlist, but I am fairly sure they do.
